How to remove carpet glue from concrete before an epoxy or polyaspartic coating. On this church gym job the glue was soft and sticky, almost like bubble gum, some of the worst we’ve seen. Here’s exactly how we got it down to bare concrete: scraping the thick spots, grinding with PCDs on our Forte grinder, and a dust control trick that keeps your tooling cutting.
In this video:
• How to tell what kind of glue you’re dealing with (soft & tacky, thin & hardened, or black mastic)
• When to scrape first, and why it saves your tooling
• What PCDs (polycrystalline diamonds) are and when to switch back to regular diamonds
• Why we throw sand on soft glue
• Running one motor on the Forte F36 vac so the PCDs don’t gum up
• Edges and corners with a hand grinder and cup wheel
• Common mistakes and safety: silica dust, and testing old black mastic for asbestos
